US president Donald Trump will announce a decision about the future of an international nuclear agreement with Iran on Tuesday.
Here are four possible avenues Trump could take on the fate of the 2015 Joint Comprehensive Plan of Action, or JCPOA, under which Iran accepted restraints on its nuclear programme in return for the lifting of UN, European and US sanctions.
Trump could claim that Iran is not living up to the deal by pointing to last week’s revelation by Israel of what it said was evidence of a secret Iranian nuclear weapons programme, most of which was already known to the international community and UN nuclear inspectors.
The International Atomic Energy Agency says Iran is in compliance with the agreement. While senior US officials acknowledge that Iran has complied with the letter of the deal, Trump points to Iran’s ballistic missile activity and regional conduct as evidence of the deal’s shortcomings.
